Assumption
2.1 Predicted plane-of-array PSH per annum
2.1 Predicted plane-of-array PSH per annum
PSHi = Hi /Gstc
PSHi Peak sun hour, hours when solar irradiance at 1000 W/m² (1 kW/m²), which is considered "full sun" (hour)
Hi Solar irradiation received on poa / Effective plane of array solar irradiation per annum (kWh/m²)
Obtain result from simulation software
Exp: PVsyst | Photovoltaic software, Design and simulate photovoltaic systems
Gstc Constant. 1000 W/m²
From the simulation software, Hi = 1688 kWh/m²
PSHi = 1688k / 1k =1688 h per annum
2.2 Measured plane-of-array PSH per annum
2.2 Measured plane-of-array PSH per annum
Gi,k Solar irradiance in weather data table (W/m²)
ts recording interval (hour)
2.3 Expected plane-of-array PSH per annum
2.3 Expected plane-of-array PSH per annum
Same with 2.2 Measured plane-of-array PSH per annum
PSHexpected per annum = 1666.6667 h
